I'm currently in the process of fine-tuning my Plex setup and have all my movies on a Seagate Personal Cloud 3TB which I know isn't powerful enough to transcode video, however pretty much everything plays fine via DirectPlay on both my FireStick and Samsung Galaxy S7.
I subscribed to PlexPass just to support Plex in general but also to enable the trailers features. Mainly we like to be able to browse through our movie library and watch trailers of them first so that we can decide what to watch, however at least on the Firestick all trailers so far come up with the error "this server isn't powerful enough to play this content".
Is there a way to get this working, can I skip transcoding or adjust settings somewhere?
